Wiring brake controllers for balanced braking

Can be detected by:

• Trailer pulling to one side during braking
• One wheel hub getting hotter than the other
• Linings on one side wearing more than the other

Can be caused by:

• Broken wire or open circuit coil one side
• Unbalanced trailer loading
• Incorrect mechanical adjustment of one side
• Mismatched linings fitted
• Mismatched tyres
• Broken or disconnected spring in a brake assembly
• More friction one side due to extra corrosion in one brake drum
• Bearing lubricant leaking on to linings one side
• Contamination one side, E.g. a piece of broken spring or a rock embedded in lining
• Unbalanced wiring, see diagram to the left
